PIN'.

To all whom t may concern Be it known that I, HERBERT L. STEINER, acitizen of the United States, and resident of the city of Providence, inthe county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in Pins, of which the following is aspecication.

This invention relates to a pin of the type commonly known as a cuff orbeauty pin whose pin-stem instead of being hinged to swing as is usualin this class of pins is held to slide endwise through suitable bearingsin the pin body, and the object of this invention is to provide simple,practical and eifective means whereby the pin stem is yieldinglyretained in its closed position by a spring engaging an annular groovein the body of the pin stem.

lith these and other objects in view, the invention consists of certainnovel features of construction as will be more fully described andparticularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is a sectional side elevation ofa pin illustrating my improved construction. Fig. 2- is an enlargedsectional view illustrating the application of the spring for thepurpose of yieldingly retaining the pin stem in its closed position.Fig. 3- is an enlarged detail of the pin stem. Fig. 4- is an enlargedperspective view of the retaining spring.

Referring to the drawings, 1 designates the back plate of the pin body,and 2 the front plate thereof whose edge 3 is rolled over that of theback plate for the purpose of securing the two together. This back plateis provided at one end with a bearing member 4 struck outward from thisplate forming substantially a hemispherical socket having its innerportion 5 open to the space between said plates, but any other suitableor desired shape of bearing may be employed. The end wall of the socketis provided with holes or openings 6-6 in a line parallel with thelongitudinal aXis of the back plate. A somewhat cone-shaped pin pointreceiving member 7 is formed near the opposite end of this back plate byforcing the stock of the plate from the inner side outward similar tothe method of forming the bearing member 4. The inner end wall of thismember 7 is then cut away or removed as at S leaving only this end openSpecification of Letters Patent.

Application filed October 23, 1911.

Patented Oct. 29,1912?. Serial No. 656,118.

for the free entry of the pointed end 9 of the pin stem 10 as it slidesin a line substantially parallel with the face of the back plate 1. Thebody of this pin tongue 10 is enlarged or provided with a shoulder 11near its pointed end to prevent its being withdrawn through the bearingmember, and the body portion is provided near its opposite end with anannular-groove 12, the side walls 13 of which groove, bevel or tapergradually to permit the pin to be readily withdrawn when this groove isengaged by the retaining spring presently described. This end of the pinmay be reduced as at 14 to permit the ball or head 15 to be swagedthereon after the pinhas been positioned in its bearing 4. In order toyieldingly engage and retain this pin stem or tongue in closed positionin its bearing, I have provided a spring 16 formed preferably of flatstock and bent into substantiallya hollow square, see Fig. 4, withportions 17 and 18 on opposite sides adapted to fit up into the openmouth 5 of the socket, and grip the edges thereof by spring pressure toassist this spring to remain in position. One end 19 of the springextends upward to engage the annular recessed portion 12 in the body ofthe pin stem, and the opposite end 17 is bent inward and then upwardforming a shoulder 21 to rest against the back plate outside of thesocket and the end 17 to engage the inner wall of the socket. The baseportion 2O of this spring is adapted to set against the inner face ofthe front plate 2 whereby when the front plate is placed in position andsecured to the back plate the opposite shoulder portion 2l of thisspring is bound and held against the inner face of the back platethereby securely retaining this spring in position without the use ofsolder, rivets, or other means of fastening.

By providing an annular groove in the body of the pin stem and alsoforming the walls of said annular groove tapering or beveled permits thepin stem to be withdrawn without rst necessitating its being turned orrotated rto any particular position axially. In other words, if thenotch or recess were on one side only of the pin stem, and 'this ndtchwere formed with square sides or shoulders, it would necessitate theturning or rotating of the stem to a certain predetermined positionbefore it could be engaged and retained by the spring end, and thenturned to another predeter-l mined position before it could be withdrawnfrom its locked position, which construction would be entirelyimpracticable in small pins of the size usually employed. Then again, byconstructing my retaining spring. so that the engaging tongue portion 19is permitted to move with the endwise niovenient of the pin stem enablesthe spring to be withdrawn from the notch portion much more readily thanas though this end were rigidly supported against this lateral movementand were permitted only to receive an endwise movement, that is tow'ardand from the front of the pin. Y

My imjproved construction of pin has many practical advantages .over theold style swing joint pin, among others being that the point of the pinwhen in its closed plate,

position is entirely covered and concealed and is securely lockedagainst any amount of strain that could be applied to the pin body towithdraw it, thus obviating the use of complicated locking devices.

Another object of the invention is that the pin may be very readilyremoved from engagement with the fabric ot' the wearer. A pin of myimproved construction may be manufactured with less expense than the oldtype of swing joint pin-tongue.

I claim:

1. A pin comprising a back plate, an ornamental front plate-secured tosaid back bearing member struck outward therefrom the latter plate beingprovided with a forming a socket, the end walls of said socket beingprovided with openings, a pintongue mounted to slide endwise throughsaid socket openings, and a spring having a body portion supportedbetween the front and-back plates and retained in position by the unionof said plates and having one portion extending into said socket toengage and yieldingly retain said pin-tongue in position by friction.

2. A pin comprising a back plate, an ornamental front plate secured tosaid back plate, the latter plate being provided with a bearing memberstruck outward therefrom forming a socket having its inner portion opento the space between said plates, the end walls of said socket beingprovided with openings, a pin-tongue mounted to slide endwise throughsaid socket openings, the body of said pin-tongue being provided with anannular groove a short distance in trom its head end, and a springhaving its engaging end projecting into the socket and adapted to engagesaid groove in the pin to yieldingly retain the pin in its closedposition, the body of said spring being supported in position by theinner face of the front plate.

In testimony whereof I affix my signature in presence of two witnesses.
